Pneumatic Tri-Eccentric Butterfly valves incorporate a triple-offset design, where the stem axis deviates from both the disc center and the body center, and the sealing surface is inclined. This configuration reduces friction during operation, enhancing sealing performance and extending valve life. Constructed from materials like carbon steel and stainless steel, and equipped with metal or PTFE seats, they are suitable for demanding applications in industries such as petrochemical, natural gas, and power generation.
